Pelvic organ prolapse

Any mummies experience(d) pelvic organ prolapse? For me is like there is a lump/bulge at the opening of my vagina. Have yet to give birth (c-sect in less than 2 weeks) and my gynae said it will go away after baby is out, but quite concerned that it wouldn't... Doesn't hurt or feel uncomfortable if i don't bother it, but it's uncomfortable during intercourse. (stopped a month ago) i guess i'm just looking for some reassurance that it will go back to normal after birth...
